strengthen
💪 增 = add/increase + 强 = strong → add strength = strengthen
增 means add or increase (土 earth piling up); 强 means strong or powerful. Together they literally mean add strength, which extends to enhance, boost, or reinforce.
增 — earth 土 + 曾 (phonetic, 'layer/repeat')
A semantic-phonetic compound: 土 ('earth') gives the meaning, while 曾 supplies the sound and hints at 'layered, piled up.' The original sense was piling earth higher and higher, which generalized to 'increase, add to.' 曾 itself depicts a tiered steamer, reinforcing the idea of stacking.
强 — bow 弓 + elong 㔾 + insect 虫
Originally written 強, depicting a type of strong-shelled insect or weevil, with 虫 (insect) as semantic and 弘 as phonetic. The meaning shifted from the insect's tough shell to the general sense of 'strong, powerful, forceful.' The form 强 is a common variant where 弘 is replaced by 弓+口.
